feat(stage15): implement CLI with search, status, report, sources, claims, list, delete
- argparse subcommands: help, search, status, report, sources, claims, list, delete - httpx client with NSCT_API_URL env var (default http://localhost:8080) - ANSI colored output: green/completed, red/failed, yellow/running - search command with --depth (quick/normal/deep) and --language (de/en) - Polling loop for search with Ctrl+C interrupt - ASCII table formatting for sources/claims/list - Connection error handling with clear messages - 28 tests for all commands and helper functions
